When you're recording the trackpoints, is the DG-200 able to get a fix? Is the green light flashing? At all times? Or sometimes?What is the test environment? Are you surrounded by any tall trees?Is the device fully charged?Have you tried resetting the unit by turning it off and turning it back on?

The DG-200 had a permanent fix (green light flashing all the time). There were no trees, no buildings. The device was fully charged. I made several tests during a week, at different places, and got similar results. It works correctly only when I use it in my car, so I suspect that it is a problem with the "static navigation" parameter that is activated. I have found in this forum : http://www.pocketgpsworld.com/bt338.php that there was a similar problem with your BT-338 device, and that you solved it :

“Static Navigation” is a feature of the chipset that freezes your position when you are moving slower than 4 km/h . Position changes will only be registered when the difference exceeds 50 meters. As a result when you walk slowly your position seems to be frozen and it updates only every once in a while.We have heard that the current batch of BT338 receivers are delivered with Static Navigation disabled, so you should not even see that effect any more.

Can you tell me if the static navigation is activated in the DG-200, and if yes, how to disable it ?

I have send a .gsr file to your email address.It contains two tracks.The first one has been created with "the distance must be more than 1 meter from the previous waypoint", and the second one "every second".

I didn't erase all data from the unit after reflashing the software, but I did turn it off and turn it back on.

And yes, I have the WAAS/EGNOS function enabled, because I want the maximum accuracy.

I also am having problems getting all the points from my DG-200.The firmware version on the DG-200 is F-GPS-03-1009062.The usb-serial driver that I am using is "Prolific" version 3.3.1.152My DG-200 utility version is 1.2.2.110510.Any progress on this problem?

Just a couple of questions:When you tried acquiring the trackpoints from the DG-200, did you get an error? If so, can you please post a screenshot?Are you using the Data Center program (http://www.usglobalsat.com/store/download/677/datacenter.zip) to get the DG-200? What is the version of this software?Moreover, are you having the same problem as this end-user has stated?

When acquiring points no error messaage came up.I am using the DataCentre software - version: 1.2.2.110510.It does appear that I am having the same problem as jcr83.Like him/her I can get trackpoints faithfully recorded and downloaded via gpx every 10sec on my Nokia 6800 Symbian using ViewRanger.Do you want screenshots of DataCentre Settings

Can you also please confirm what are the config settings of the DG-200? And yes please, you can post a screenshot of it. To do this, just open up the DataCenter and click the Connect button. Then, go to Device and select Setting.

Have you tried deleting all trackpoints from the unit? Also, have you configured all the settings back to 0, except making the DG-200 record every 1 second (By time)? Were you able to get the same results?

Thanks for the DataCentre link. Have downloaded and installed latest version. Put settings to 0 as suggested except timing 1s. Great! Picked up 654 points. But it was a mixed car journey(25mph) and walking. The car part comes out with a smoother route on Google. The walkabout in town is a series of spikes. Why should this be? I have 'disable data logging if distance....' still checked. Will uncheck and see if this helps on the walking. How can I send you the gsr and gif?Thanks for your help!
